Abstract: Improvements are disclosed for a load-clamping system with variable clamping force control by which a wide variety of dissimilar loads of different types, geometric configurations and/or other parameters can be accurately clamped at respective variable optimal clamping force settings. An operator terminal cooperates with a controller to translate one or more possible load parameters into a form easily discernible visually by a clamp operator and preferably easily comparable by the clamp operator, from his visual observation, to each particular load which he is about to engage, so that the clamp operator can interactively guide the controller in its selection of an optimal clamping force setting for each particular load.

Abstract: A roller load support, for mounting on a load carrying vehicle such as a lift truck, has an elongate frame with a forwardly tapering vertical thickness and an upper surface for insertion beneath the underside of a load. Different longitudinally spaced pluralities of transverse upper rollers are movable upwardly to protrude through the frame's upper surface to engage the underside of the load during the insertion process. During the insertion process, the upper rollers are pushed upward by corresponding different pluralities of transverse lower rollers which rotatably engage the floor or other surface beneath the frame and frictionally counter-rotate the upper rollers. The lower rollers are spaced nonuniformly relative to each other along the length of the frame, with such spacings increasing progressively in size, within each plurality of lower rollers, in a forward direction toward the front end of the frame.

Abstract: Improvements are disclosed for a load-clamping system with variable clamping force control by which a wide variety of different load types in a wide variety of different load geometric configurations can be accurately clamped at respective variable optimal clamping force settings dependent on each load's respective load type and geometric configuration in combination. An operator display and input terminal cooperates with a controller to translate assortments of possible load variables into a form easily discernible visually by a clamp operator and preferably easily comparable by the operator, from his visual observation, to each particular load which he is about to engage, so that the operator can interactively guide the controller in its selection of an optimal clamping force setting for each particular load.

Abstract: A lift truck clamp arm assembly for engaging large cartons, which may contain large household appliances. Pivoting clamp pad support assemblies are adjustable to vary a radial spacing between a pivot pin and a clamp pad supported on the clamp arm assembly by attachment to the adjustable clamp pad support assembly, to provide desired pressure concentrations at selected parts of a carton to be gripped.

Abstract: A hydraulic rotating and braking system for a lift truck-mountable load handling assembly has a hydraulically-driven worm screw with a hydraulic motor located adjacent one end of the screw and a friction brake located adjacent the opposite end of the screw. The system includes a friction brake having a brake controller located at least partially within the worm screw. The friction brake is releasable by the exhaust of fluid without the need for a fluid exhaust line extending to the lift truck's reservoir tank.

Abstract: A fork positioner, usable alternatively either as an attachment to an existing load-lifting carriage with forks, or as part of the original equipment of a load-lifting carriage, has a pair of elongate hydraulic piston and cylinder assemblies mountable in an interconnected parallel relationship between an upper transverse fork-supporting member and a lower transverse member of the carriage. Each of a pair of fork-positioning guide members has a fork-engagement surface movable by a respective piston and cylinder assembly and connectable thereto so that the fork-engaging surfaces face substantially perpendicularly away from an imaginary plane containing the respective longitudinal axes of the piston and cylinder assemblies. An exemplary carriage mounting the fork positioner is also disclosed, together with a wireless hydraulic function control system for use with the fork positioner or other multi-function load handlers.
